The Lowdown
Alright folks, Rusty here. Let's be straight up about Kennebunk Beach. We’re looking at a pretty bleak 16-day stretch, to be honest. The data shows that for the first nine days, there's just nothing doing. From Tuesday the 11th through to the following Wednesday the 19th, it’s a flat, choppy mess. We're talking wave heights barely cracking 2ft, mostly with junk wind and cross-chop. You’d be wasting your time paddling out. There is a small window that shows up Thursday morning, August 20th, where we get a little bit of life, but I gotta warn you, it’s not a standout.
That Thursday morning is really the only thing close to a highlight. Kennebunk Beach will see some 2ft swell coming from the SE, with a period of 11 seconds. It’s not gonna shake the earth, but the combined swell energy is around 187, which is moderate, and the wind goes glassy with that ENE breeze. That’s clean. The water temp is running at a toasty 69°, which is a touch warmer than normal for this time of year, so that’s a nice bonus. For the rest of that day and into Friday morning, August 21st, we’ve got clean, cross-off conditions, but the swell stays small, around 3ft. It’s surfable, but only just.
Now, the week after that doesn’t get any better. From the 22nd through the 26th, it’s back to onshore slop and very weak energy. There’s a bit of offshore wind on Monday the 24th, but the swell is just too weak (3ft) to make it worth the effort. The long-range stuff is a no-go. Honestly, for Kennebunk Beach, this is just a flat spell. The break is sheltered and fairly inconsistent, so blanks like this are part of the deal around here. Don’t get your hopes up, but forecasts can change, and it never stays this poor for too long.
Stay patient.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
